Computing Divided: How Wide the Chasm?
Four years have seen accelerating division and growing fissures driven by international geopolitics and increasing technology and trade restrictions. The world is at an inflection point. What should ACM do? View full article
Computing's Grand Challenge for Sustainability
The computing community should embrace a grand challenge to reduce the carbon-emissions and environmental impact of computing in absolute terms dramatically, and if possible, to zero. View full article
Five Years as Editor-in-Chief of Communications
This is my last editorial as Editor-in-Chief of Communications, so it is a moment to share learnings and, of course, to reflect on accomplishments. View full article

To fulfill its responsibility as the world's preeminent computing professional society, the ACM must transform itself to lead. View full article
Is the Global Computing Community Irrevocably Divided?
The powerful forces pulling the global computing community apart have broad implications on all seven continents, not just in the U.S. and China. View full article
Good, Better, Best: How Sustainable Should Computing Be?
The grid faces major challenges to decarbonize, and the computing community can and should help accelerate the process. View full article
Time for Two Annual Turing Awards
ACM should bestow two Turing Awards each year, starting immediately. View full article
Around the World
In 2017, we made the strategic decision to launch Communications' Regional Special Sections. In April 2021, we will publish the special section for Arabia, completing our circumnavigation of the world. The special sections have emerged as a "multicultured splendor." View full article
Driving the Cloud to True Zero Carbon
Climate change has come to the fore as a business concern, and this compels the business leaders of computing technology companies to be on the side of progress toward true zero carbon. View full article
2021: Computing's Divided Future
China and the West's fundamental systemic differences and growing geopolitical competition are increasingly open. The new reality is pulling the computing community apart, and spilling over into the academic and research communities. View full article
What Do DDT and Computing Have in Common?
In addition to reaping computing's bounty, we should "own" and work to reduce the negative impacts of computing. Both carbon emissions and e-waste are growing fast and need attention! View full article
Cracks in Open Collaboration in Universities
Universities and the interchange of scholars and students in international collaborations have long played an important role in knitting a fabric of human relationships and shared understanding. This fabric is fraying rapidly. View full article
Sustaining Open Collaboration in Universities
Increasing international tension and distrust, and its projection into universities, is eroding open collaboration and inquiry. View full article
In November 2017, we launched Communications' Regional Special Sections. A year and half later, I'm happy to report we're halfway around the world and gaining momentum! View full article
Owning Computing's Environmental Impact
It is time for the computing community to face up to computing's growing environmental impact—and take responsibility for it. View full article
Open Collaboration in an Age of Distrust
We are manifestly in a new era of international relations—"An Age of Distrust"—where the trend toward increased trade and integration has stalled, if not reversed. View full article
Introducing Communications' Regional Special Sections
I am pleased to introduce the first regional special section of Communications, which we hope will become a feature that you anticipate and enjoy, and of course value for the insights and perspectives it presents! View full article
Computer Architecture: Disruption from Above
For the research community, opportunities to shape a profoundly different, new age of computer architecture are emerging. View full article
I was fortunate to enter computing in the era of site funding by the Defense Advanced Research Projects Administration, whose sustained investment of $10M/year (inflation adjusted) enabled the undertaking of bold transformative ideas. Large-scale funding enables examination of larger questions that cross problem spaces, systems, abstractions, even fields. I believe the need for large investments has never been greater.

Here Comes Everybody . . . to Communications
I am pleased to announce a new Communications of the ACM initiative to expand the Communications community globally. Why? To include important voices and perspectives in the conversation about the present and future of computing. View full article
Computing Is the Secret Ingredient (well, not so secret)
Computer science is both a powerful enabler of rapid advances in all intellectual fields and a disruptor driving furious revolutions in commerce and society worldwide. View full article
Computing Is a Profession
The notion of what constitutes a profession has been studied extensively through exploration of its attributes. Common among these are a deep technical expertise, an essential, valued, societal contribution, and the need to adhere to high ethical and technical standards. Computing exhibits all of the attributes of a profession. View full article
Building the Future Communications of the ACM
The Communications of the ACM team is dynamic; a collection of passionate leaders, making change and creating the future CACM through the actions, initiatives, and goals that we are pursuing today. In that vein, here are some of my ambitions for the Future CACM. View full article
Today's Communications of the ACM
